A coupling for multi-wall, corrugated pipe, the pipe including a corrugated wall having a plurality of primary corrugations, is disclosed. The coupling includes a first pipe section having disposed at one end a bell portion, the bell portion having a portion of the corrugated wall and an outer wall; a second pipe section having disposed at one end a spigot portion, the spigot portion having a portion of the corrugated wall between an inner wall and an outer wall; and a gasket engaged between the corrugated wall of the bell portion and the outer wall of the spigot portion. A multi-wall, corrugated pipe section, and method for assembling a plurality of multi-wall, corrugated pipe sections, are also disclosed.

A coupling for multi-wall, corrugated pipe, the pipe including a corrugated wall having a plurality of primary corrugations, is disclosed. The coupling includes a first pipe section having disposed at one end a bell portion, the bell portion having a bell portion of corrugated wall and an outer wall; a second pipe section having disposed at one end a spigot portion, the spigot portion having a spigot portion of corrugated wall between an inner wall and an outer wall; and a gasket disposed in a groove extending around a circumference of the spigot portion and engaged between the bell portion of corrugated wall and the spigot portion of corrugated wall. A multi-wall, corrugated pipe section, and method for assembling a plurality of multi-wall, corrugated pipe sections, are also disclosed.

A system is disclosed for manufacturing multi-wall corrugated polymer pipe. The system includes an extruder configured to co-extrude concentric annular tubes; a corrugator configured to form the concentric annular tubes into a dual-wall pipe having a smooth wall and a corrugated wall; a cross-head die configured to extrude an outer wall of pipe onto the corrugated wall of the dual-wall pipe; a vacuum punch configured to penetrate the outer wall of pipe and draw a vacuum between the corrugated wall and the outer wall, such that the outer wall of pipe deforms inward toward the corrugated wall of pipe between bell and spigot portions of the corrugated wall; and a cutter configured to cut the pipe into sections where the vacuum punch deformed the outer wall between the bell and spigot portions of the corrugated wall. A method of manufacturing multi-wall corrugated polymer pipe is also disclosed.

A method of pressing an outer wall of polymer pipe is provided. The method includes extruding a layer of polymer onto a pipe to form an outer wall of pipe; conveying the pipe including the outer wall of pipe through a pressing apparatus having a pressing element configured to rotate about the pipe; and urging the pressing element against an exterior surface of the outer wall as the pressing element rotates about a pipe conveyed through the pressing apparatus. An apparatus for pressing an outer wall of polymer pipe is also provided.

Cover for house shutters

A portable carrier for a beverage container has a base member with an open top and closed bottom, the open top communicating with a cavity defined by an upper portion of selected cross-sectional dimension and a lower portion of reduced cross-sectional dimension providing an internal ledge, the base member having external integral opposed boss portions having openings therethrough. A cover member has a closed top and open bottom with a cavity therein communicating with the open bottom, the cover member telescopically mating with the base member when in the closed position, the cover member having integral external opposed boss portions with openings. A cord extends through the openings in the boss portions of the cover member and the base member with knots at the ends thereof so that thereby the cord serves the dual function of providing means for carrying the portable carrier as well as preventing inadvertent misplacement of the cover member. A beverage container can be positioned in the base member to rest on the internal ledge. Ice can be placed in the base member lower portion to cool the beverage in the container.
